The article discusses the designs and methods of manufacturing centrifugal compressor impellers. The main disadvantages of welded and welded-brazed structures are highlighted. As an alternative, the authors of the article proposed the design and manufacturing technology of a composite impeller. The advantages of this design are given. The results of calculations of the stress-strain state of the impeller are presented. A comparative analysis of manufacturing technologies for a composite impeller made of steel 36NiCrMo4 and welded impellers made of steel X5CrNiCuNb16-4 and AISI 301 was carried out. The cost of the proposed alternative impeller is estimated in comparison with welded structures. The manufactured composite impeller was tested on an acceleration stand. The tests were conducted with a simulated fit of the impeller on the rotor shaft with interference. This simulation provides the impeller with a load equal to the interference fit on the rotor shaft. The developed technical solution for a composite impeller of a centrifugal compressor makes it possible to use materials not intended for welding, eliminate metal embrittlement, maintain the isotropy of the mechanical properties of the materials used, control the stressed state of the components, eliminate the main stress concentrators on the cover disk and reduce the stress level in the concentrators on the main disk, improve manufacturability and reduce the cost of the finished product. At the same time, the permissible maximum peripheral speed and efficiency increase in comparison with welded.
